Anion-enhanced excited state charge separation in a spiro-locked N-heterocycle-fused push-pull zinc porphyrin (open access)

Anion-enhanced excited state charge separation in a spiro-locked N-heterocycle-fused push-pull zinc porphyrin

This article presents a new type of push–pull charge transfer complex, viz., a spiro-locked N-heterocycle-fused zinc porphyrin, ZnP-SQ, that is shown to undergo excited state charge separation, which is enhanced by axial F⁻ binding to the Zn center. Spectroelectrochemical studies are used to identify the spectra of charge separated states and charge separation upon photoexcitation of ZnP is established.

Anti-racist Pedagogy in Art Education: K-12/Higher Education captions transcript

Anti-racist Pedagogy in Art Education: K-12/Higher Education

Video recording featuring co-hosts Lauren Cross, Ph.D., and Kathy Brown, Ph.D., engage in ongoing conversations about anti-racist pedagogy in the arts and design. Joined by distinguished guest panelists, Joni Boyd Acuff, Ph.D., and James Haywood Rolling Jr., Ed.D., this first installment of the 2044 series introduces Afrofuturism and the ways that it can help reimagine art discourses, laying the groundwork for establishing Afrofuturism as a framework for conceptualizing and enacting anti-racist art education practice. In addition to sharing their work and how it relates to Afrofuturism and futurist thinking, the panelists discuss how recognizing Black and Brown artists and advocating for racial literacy is essential to creating and maintaining a racial consciousness practice in K-12 education.

Automated Approach to In Vitro Image-Guided Photothermal Therapy with Top-Down and Bottom-Up-Synthesized Graphene Quantum Dots (open access)

Automated Approach to In Vitro Image-Guided Photothermal Therapy with Top-Down and Bottom-Up-Synthesized Graphene Quantum Dots

Article discusses how, based on recent studies, graphene quantum dots (GQDs) are expected to possess advantageous photothermal properties and facilitate fluorescence image-tracking in the visible and near-infrared (NIR), while surpassing other graphene-based materials in their biocompatibility. The combination of the photothermal and imaging modalities tested in vitro makes the GQDs developed in this work prospective agents for cancer theragnostics.

Caputo Fractional Derivative and Quantum-Like Coherence

This article studies two forms of anomalous diffusions and discusses the joint use of these prescriptions, with a phenomenological method and a theoretical projection method, leading to two apparently different diffusion equations. The authors prove that the two diffusion equations are equivalent and design a time series that corresponds to the anomalous diffusion equation proposed.

Disentangling Orbital and Valley Hall Effects in Bilayers of Transition Metal Dichalcogenides (open access)

Disentangling Orbital and Valley Hall Effects in Bilayers of Transition Metal Dichalcogenides

This article shows that a bilayer of 2H-MoS₂ is an orbital Hall insulator that exhibits a sizeable orbital Hall effect in the absence of both spin and valley Hall effects. The results are based on density functional theory and low-energy effective model calculations and strongly suggest that bilayers of TMDs are highly suitable platforms for direct observation of the orbital Hall insulating phase in two-dimensional materials.
